Upgrade your BMW with Dinan's performance springs, a total package approach that preserves the original driving feel while delivering balanced and enhanced performance.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge (Ride Quality Kit is worth 1 point).

After much anticipation, we are pleased to release our lowering spring kit for the BMW M3 G80 platform! Taking our experience from our highly popular F80 springs, the goal with this offering was to lower the M3 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal. 

Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.
